'Karma's a bitch,' said Breitbart's Milo Yiannopoulos on Instagram as star continues to face online attacks.

Leslie Jones: Celebrities on Twitter show support for Ghostbusters star using #LoveforLeslieJWochit

Saturday Night Live and Ghostbusters star Leslie Jones has been forced to shut down her own website after a hacker posted nude photos of her along with an image of her driver's licence and passport.

The hack of Jones' website follows a string of racist and sexist Twitter attacks against the black comedienne, allegedly inspired by insults doled out by alt-right writer Milo Yiannopoulos, a tech editor at the Breitbart news website.

The conservative website was edited by Steve Bannon until he recently stepped down to run Donald Trump's campaign. Yiannopoulos often refers to Trump as "Daddy."

In a review of the Ghostbusters reboot, Yiannopoulos said the character of Patty Tolan played by Jones was "a black character worthy of a minstrel show."

Some of the Twitter posts compared Jones, 48, to a gorilla. In the new assault on Jones' web page, the hacker posted a video of Harambe — the gorilla shot to death at Cincinnati Zoo this summer — at the top of the site.

The nudes were Jones' personal shots, and were possibly accessed from the Cloud. An FBI spokesman said the agency is aware of the attack and is "assessing" the situation, the New York Daily News reported. Meanwhile, Jones temporarily shut down her account.

"I leave Twitter tonight with tears and a very sad heart," she wrote. "All this cause I did a movie. You can hate the movie but the s--t I got today ... wrong."

"People should be able to express diverse opinions and beliefs on Twitter," read a statement from the company. "But no one deserves to be subjected to targeted abuse online, and our rules prohibit inciting or engaging in the targeted abuse or harassment of others."

The day Jones' website was hacked, Yiannopoulos posted on Instagram: "Karma's a b---h." He then followed it with another post which read: "S--t just heard about Leslie Jones. Had no idea!!! Ignore that karma thing lol."

Fans, colleagues and supporters have rushed to Jones' defence. After the Twitter attacks, Ghosbusters reboot director Paul Feig tweeted that Jones is "one of the greatest people I know. Any personal attacks against her are attacks against us all."
